personnel to carry out repair and replacement of
serviceable parts to be available upon request.
1.02 The Chair shall be able to to be positioned at any
seat height between 20" and 35" from the floor. While
reclining, the seat shall automatically tilt and toeboard

2.00 OPERATION
2.01 The chair is hydraulically operated, quiet in operation
and provides a stable foundation for both the patient
and additional dental equipment. It provides mounting
capability for right or left hand fixed units. The hydraulic
system consists of 2 cylinders (one to control lift and
another to control tilt) and is sealed to prevent leakage
of hydraulic fluid. The 3000 Series chair lifts a minimum
of 350 pounds. The 3300 Series chair can lift up to
450 pounds. Potentiometers and electrical switches
guarantee repeatable operation when the operator
depresses the foot or touchpad switch. Movement
rates are controlled by a hydraulic control valve, which
is set and tested at the factory. Potentiometers can be
adjusted in the field to alter factory settings for incline,
recline, up and down travel. The fluid reservoir is
blow-molded to eliminate seams. Tubing is secured to
barbed fittings and restraining clamps are used where
necessary.
2.02 Power to the unit shall be 115 volts or 230 volts (voltage
configuratons are built and set at the factory). The power
is delivered to a microprocessor controlled, printed
circuit board. Software in the microprocessor controls
the movement of the chair.
2.03 Positioning of the patient shall be by an electronic foot
control that is easy to program. It shall be attached
to the chair base and provide easy positioning. The
integrated touchpads, located in each of the arm
supports, are illustrated with icons that indicate the
four positioning functions; incline, recline, chair-up,
chair-down. Also present on the touch pad are icons
for operating the dental light, chair swivel electric lock
and programmable positions. The icons are raised to
allow for quick location and good tactile feel. The foot
control is sealed to prevent contamination from liquids
or dust.
2.04
The chair swivels a minimum of +/- 30 degrees from the
center of the chair. The chair brake swivel shall have
seven detents of 10° and will lock the chair in position
at each detent upon releasing the electric lock button.
2.05 The chair shall come from the factory with four auto-
positions. By pressing and releasing the auto button,
the chair moves into the desired position. Auto-positions
are programmed by adjusting the chair to the desired
position and pressing and holding the corresponding
auto-button until beeping occurs.
2.06
Either the touchpad or the foot switch can be used to
bring patients to an upright position for consultation,
rinsing or impression making and then return patient
to the previous operating position.
2.07 Two strategically located lower truss cover switches
stop the automatic chair positioning activity if the truss
mechanism encounters an obstacle. The doctor can
also stop the chair movement by activating any of the
other icons that trigger chair movement.
